Specifically designed for use with 3 bolt tubular header sets, GT2 Spec Type, (which I also stock) this uppipe will give significantly better spool, crisper response and greatly improve torque across the whole rev range with no loss of top end bhp.
Ask anyone who has one fitted.
All my uppipes are stainless steel, slip jointed, DEI heat wrapped with five new studs.
The slip joint greatly reduces the possibility of blown gaskets or cracked welds.
3 bolt gaskets available if required.
£155. Next day delivery £12.50.

Harvey can you supply one of these for an MD321x (V on smaller exhaust housing so half way from a T to V basically) looking for spool not top end as its on a 2.5 currently at 440 on your ported headers and up-pipe (up-pipe originally spec'd for APS SR40) would. Like to hit high 400's ideally.

How much are the headers?

Cheers.

 

Uppipe as above.
3 bolt header set £445.

 

Harvey I've bought some api Ported oem headers from a member here to go on my wagon along with a 3" decat pipe (twin collector type) which narrows to 2.5. I was considering one of your flow matched up pipes to go with them. Do you think it would be of benefit? Would be flowed for a td05. What prices for these pipes ? Thanks.

 

What uppipe are you using at present?
The uppipe I would supply for ported headers and TD05 16G turbo would be stainless steel, slip jointed, DEI heat wrapped with five new Subaru studs. £145 plus delivery.
Let me know the uppipe you are using and I will advise if it is worthwhile changing.

 

Hi Harvey. Thanks for replying, I just have the standard headers and up pipe fitted ATM. So i would prob just use the original up pipe when I fit the headers but I'm wondering if the standard up pipe will undo the work of the ported headers and wether it is worth having one of your pipes. Andy f mapped my wagon to 315 @1.3 bar and said with fmic and induction we could maybe max the turbo at 340 or so. So I have fmic and k&n induction kit along with the api ported headers and a 3" decat pipe all to be fitted before another map from Andy. I'm hoping for another 30 bhp or so and a bit of faster spool as it doesnt really come alive until 4000 rpm. Do you think that's achievable with the parts listed? Your advice is appreciated, thanks.

 

When I originally started porting Subaru headers I also ported the uppipe and the results were quite impressive but I then invested in flow bench time and much to my surprise I found the standard uppipe was not particularly good. I then tried some aftermarket uppipes but in the end designed a range of 6 slip jointed uppipes to go with ported headers or small bore tubular headers (but not the larger diameter GT, GT2 and Gruppe S type). The improvement from the performance purpose designed uppipe over the OE Subaru uppipe is quite noticable.
I cannot tell you how much the uppipe will add but it will make your car more responsive with marginally earlier spool and better top end breathing and because you will have more torque you also have improved BHP.
Providing you fit an efficient front mount intercooler ie. Hybrid, you will get a further power increase and fitting the FMIC will hold you in good stead for future improvements.
I cannot say what improvement you will get exactly on your car and I am not sure that I know the model or year but on an STi 3 Wagon running 392 bhp on an STi 8 TMIC, we did back to back tests with a Hybrid GT FMIC (not GT2 the most recent developement) The car was mapped on the STi 8 TMIC with 392 bhp. The Hybrid GT was fitted and the car immediately ran 401 bhp on the same rollers at TEG Sport/Steve Simpson. Steve then adjusted the map and we ended up with an easy 410 bhp. Remember this was starting from an STi 8 TMIC.
Generally 93-96 cars will benefit from an efficient FMIC by the time they get to 280-300 bhp. STi 3 and 4 show a definate benefit beyond 300 bhp and STi 5 and 6 need an efficient FMIC by 320 bhp. On New Age cars the WRX TMIC is good for a bit more but by 350 to 360 bhp there is a clear case, even on an STi for moving to FMIC in that power bracket.

Hi Harvey
At the moment I'm Ian sti8 with fmic and your ported heads and uppipe
420 hP 396 torq on v power 460 hp 430 torq 20 %meth
Would I see Gaines in spool power torq with a different uppipe headers combo?
Regards mick

 

You don't tell me what turbo you are running?
The 3 bolt Trick uppipe is for use with tubular 3 bolt header sets and will not fit ported OE headers or any other 2 bolt header set.
There is also a 2 bolt Trick uppipe but that is for use on tubular header sets which have a large diameter collector, far bigger than that on the OE headers.
Let me know what turbo you have.

 

Harvey
Billet sc46
I was thinking more the full set up ...
Headers and uppipe
Both oe ported from yourself at the moment
Just wondered if I should be on a better set up ?
Mick

 

Harvey
Billet 46 early model
I was thinking swapping both uppipe and headers
As on your ported versions at min.
What's the best option ?
Headers and uppipe please
Mick

 

Absolutely worth every penny of the price,I saw a very good increase in both spool and torque across the rev range after fitting Harvey's trick 3 bolt uppipe!

 

Hi Mick. Cheers Ryan.
The ported headers are obviously doing a good job but as you move up the scale then greater benefits are available from an efficient set of tubular headers and these will give reduced back pressure.
Depending on turbo and capacity a ball park area to change from O/E ported to tubular (subject to design) is around 400 bhp.For the best possible results on the SC46 which we have a lot of experience with, here is what you need :
GT2 Spec Type Headers.
DEI heat wrapped.
Trick 3 bolt uppipe for header/SC46 Combination.
Regardless of money I know of no header/uppipe combination that will outperform this on your SC46.
Come back with any other questions.
All in stock and ready to fly out the door.

 

At Scooby Clinic today. Car running V-Power. SC54 turbo. Originally fitted with 3 bolt tubular header set and supplied uppipe. See the difference the Trick uppipe gives.
Significantly earlier spool, more torque right across the rev range and even increased top end power.
Gains on 400 bhp setups are equally impressive and remember there is now a 2 bolt "Trick" uppipe giving similar gains for those that have the original GT1 Spec type /Gruppe S 2 bolt header sets.
